How to reproduce

Bug Report:

CLI validation error "Relative extruder addressing requires G92 E0" occurs incorrectly for all inputs including GUI-created 3MF files

got error when validate: Relative extruder addressing requires resetting the extruder position at each layer to prevent loss of floating point accuracy. Add "G92 E0" to layer_gcode.

Description

CLI mode validation errors with "Relative extruder addressing requires resetting the extruder position at each layer to prevent loss of floating point accuracy. Add G92 E0 to layer_gcode" for all slicing operations, including:

Slicing GUI-created 3MF files
Slicing STL files with valid profiles
Even with --no-check flag

Same operations succeed in GUI with the same settings profiles.

In other words, this is a problem only using CLI.

Steps to Reproduce

Scenario A - From GUI-created 3MF:

Open OrcaSlicer GUI
Load a model file
SLICE successfully, then save as .3mf project
Close GUI
Run: orca-slicer --slice 0 saved_project.3mf
Expected: Slicing completes successfully
Actual: Error - "Relative extruder addressing requires resetting the extruder position..."

Scenario B - From STL:

Download official OrcaSlicer profiles from GitHub OR use exact OrcaSlicers from the OrcaSlicer.app/ folders in MacOS
Run: orca-slicer --slice 0 --load-settings "machine.json" --load-settings "process.json" --load-filaments "filament.json" model.stl
Expected: Slicing completes successfully
Actual: Error - "Relative extruder addressing requires resetting the extruder position..."

Additional Notes

--no-check flag does NOT bypass this error
Error occurs even with 3MF files created and saved from the GUI
We also found that using semicolon-separated paths for settings failed to local on-disk files, i.e. --load-settings "path1.json;path2.json" and instead needed to be passed with multiple instances of the --load-settings flags, i.e., --load-settings path1.json --load-settings path2.json. This is unrelated to the issue above.
